achieved through the use of chiral spiroborate ester catalyst. The catalyst is applicable for both analytical and industrial purposes since it is not sensitive to air and moisture. A rapid synthetic route has been developed for the preparation of (S)-2-methyl-2,3-dihydro-1-benzofuran via enantioselective reduction of homobenzylic ketone in the presence of a chiral spiroborate catalyst as the key step.
摘要 通过使用手性螺硼酸酯催化剂可实现不对称还原高苄基酮。该催化剂对空气和湿气不敏感,因此可用于分析和工业目的。已经开发了一种快速合成路线,用于在手性螺硼酸酯催化剂存在下通过对映体选择性还原高苄基酮来制备(S)-2-甲基-2,3-二氢-1-苯并呋喃。
